What Types of Filling Materials Are Available? Today, several dental filling materials are available. Teeth can be filled with gold; porcelain; silver amalgam (which consists of mercury mixed with silver, tin, zinc, and copper); or tooth-colored, plastic, and materials called composite resin fillings.

When trying to decide which type of filling is best suited for you, you need to factor in the location of the cavity in your mouth, severity of decay, cost, .

Gold fillings are very strong, non-corrosive and can last up to 15 years, with proper care. However, they are much more expensive than silver amalgam fillings and require more than one dental visit to be fitted correctly.
Silver amalgam fillings are also very strong and sturdy, however, many individuals do not find them to be aesthetically pleasing. In addition, they are more likely to expand and contract and to cause a tooth crack as compared to other types of fillings. In addition, many individuals worry about the long-term safety of silver amalgam fillings since they contain Mercury: a known neurotoxin.

Composite fillings are an attractive option because they can be closely matched to the color of your teeth. However, composite fillings are more expensive than silver amalgam fillings and are not as durable.
Ceramic fillings are made of porcelain and are a very aesthetically pleasing option that is also very durable. However, ceramic fillings cost more than silver amalgam fillings and can wear the opposing teeth if the porcelain becomes rough.
Glass ionomers (acrylic fillings) often last for less than five years but are a good choice for children if their teeth are changing. They can also release Fluoride and this helps to prevent tooth decay.
